On leaving the EU, the regulators lost access to EU data sharing and cooperation arrangements. CMA can no longer share confidential information with the European Commission or member states in merger, competition or consumer enforcement cases.28 FSA has also lost full access to the EU’s Rapid Alert System on Food and Feed (RASFF) which provides member states with information on food safety incidents. It no longer has access to ‘real time’ data on all incidents, receiving information only on UK-relevant alerts by email. These changes have increased the time and effort required to deal with food safety incidents, with FSA estimating it requires around 65% more staff resource to deliver the same international information exchange on food safety incidents now than it did before.29 HSE no longer has access to the chemical safety data underpinning the EU’s Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulations. Industry has estimated it will cost £800 million to replicate this data in the UK REACH system.30
